Title: Piloting Platform for Micro-Robot Handling (MicroPilot)

A smart colloidal particle, a 1 µm polystyrene particle that is structured on a chemical and physical point of view, is injected into a microfluidic chip embedded with a matrix of electrodes. Controlling the spatio-temporal localisation of the AC electric field allows a precise 4D handling of those smart particles so that they can interact with human cells.

Using Labview to control an electro-microfluidic plateform and the localisation of the electric field, we have achieved a precise localisation of colloidal particles which can interact with cells in order to achieve targetted drug delivery systems or tissue engineering.


Use of NI Labview, NI Vision, NI DAQmx

The Challenge:
  • Overpass the Brownian motion of colloidal particles

  • Be able to place them at deterministic position in 3D in a microfluidic chip embedded with electrodes. The force acting on the particle is called dielectrophoresis. The method used is called mobile pulsed dielectrophoresis, schematically explained:

The Solution:
  • A original technology was developped based on Lab-On-Chip processes. Electrodes are embedded directly in the microfluidic chip and are made of ITO, which conductes electricity and is transparent in visible light:

  • The chip is then inserted into an electro-microfluidic plateform consists in:
    • Leica microscope modified for bright field, dark field, fluorescence and LED transmission
    • Fluidic module: capable of injection 100 µL solution from 0.1 – 10000 pL/s
      • Interfaced with Labview via an CANUSB link
    • Electric module: capable of rerouting 2 AC/DC signals to 112 electrodes
      • Interfaced with Labview via a USB-RS232 link
    • Visualisation module: Particle Tracking Velocity system
      • Interfaced with Labview via NI-IMAQ Vision

  • The Labview program is capable of:
    • Deliver a constant pressurized flow into the microfluidic chip

    • Reroute 2 AC signals generated by 2 generators (independantly controled) to a matrix of 53*53 electrodes

    • Program a sequence of AC signals rerouting

    • Real-time control of the path of nanoparticles via a Playstation Joystick

    • Visualization and grab

  • The motion of colloidal particles can be achieved thanks to the precise spatio-temporal synchronization of the AC signals and the application on the active electrodes. The 10 µm polystyrene particle trajectory writes 'LoC' as 'Lab-on-Chip'. The trajectory is overlapped by a home-made NI-Vision porgram capable of PTV.

  • By coupling those particles with cells, drug delivery systems can be achieved such as : delivery of specific durg to a cancer cell or phagocytosis of si-ARN coupled particles (work under publication)
  • When coupled with fibronectin, particles can be used as sensors to interact with cells and induce cell differenciation when working with steam cells (work under publication)


Huge amount of work and I like the Sony touch.

Nice job


good work, very impressive !

Hey there,

Thank you so much for your project submission into the NI LabVIEW Student Design Competition. It's great to see your enthusiasm for NI LabVIEW! Make sure you share your project URL ( with your peers so you can collect votes via "likes" for your project and win. Collecting the most "likes" gives you the opportunity to win cash prizes for your project submission. I'm curious to know, what's your favorite part about using LabVIEW and how did you hear about the competition?

Good Luck, Liz in Austin, TX.


Hi Liz,

Thanks for organizing the Student competition.

I heard about the competition by searching for labview code on the net and found your webpage.

BTW it's quite difficult to make other people to vote, it appears the "like" button does not work always with all browsers...

Have fun !



BTW, I am wondering if the project is really understandable by people, any feedbacks ?

thx guys !


updated the poster for enhanced resolution !
